Happens to mine too if I let the wheel loose.
Hold it and it won't oscillate itself to oblivion.
Or you could turn the ffb gain down which won't prevent the problem.
Maybe you could increase the damping but.. again... It'll happen eventually.

What tire compound were you using?
What was your tire pressure?
What was the track and tire temperatures?

I had this on my Thrustmaster TX before the recent patch but it is much better for me now, which setting are you working with raw, informative or immersive? I found i get it more with immersive but less with the other two?

Also, how many cars are you racing against... People have reported more than 15-16 grid on xbox has caused weird feedback problems... I have notice since the patch that my wheel weight feels a lot different in private testing to race mode... Its like the xbox is struggling when there is a lot going on.. I have a new xbox one x coming next week so i will see if the extra processing power seems to make any difference.

What Settings are you using with your TX Rob? My TX shakes more with Immersive and Informative which is why I have stuck with Raw Default Settings. I haven't tried Immersive or Informative much since Patch 1.5 though.

100 /65 / 20 / 20 when racing but i turn down gain from 65 to 50 for private test sessions as the wheel seems to feel much lighter when there are other cars in track... Weird, but there you go!

That's qualifying for the ginetta jr class, so however many AI are in that.
